SAN ANTONIO – A Texas school district with multiple pending teacher-student sex cases is facing two federal lawsuits over its inability to protect students.

The most recent lawsuit involves the son-in-law of Donna Independent School District superintendent Jesus Rene Reyna – Carlo Andres Cordova, 26. Cordova was arrested last month over an alleged sexual relationship with a student at Donna High School, where he taught criminal justice, The Monitor reports.

The lawsuit, filed by attorney Ricardo Garcia, alleges Cordova’s questionable conduct with female students was ignored by school officials, and that Donna High School assistant principal Deborah Medrano failed to take action when a teacher reported Cordova’s alleged sexual relationship with his student in November.

“This guy was a criminal justice teacher,” Garcia told The Monitor. “He was supposed to be teaching these kids about the law, but he was breaking the law himself.”

The victim’s grandmother told police she was forced to cancel the teen’s phone because Cordova called relentlessly to meet for sex after the girl graduated in May. The girl later told police she was 17-years-old when Cordova had sex with her in his classroom, his family’s business, and at La Posada Inn in Alamo, The Monitor reports.

“The suit argues that the school district failed to protect the underage student’s rights and allowed ‘physical sexual contact’ by Cordova on multiple occasions including one when he ‘sexually violated’ her inside Donna High last May. As a result, the student suffered physical pain, mental anguish, and severe emotional and mental distress, the suit states,” according to the news site.

The case is one of three currently pending in the district involving school employees accused of sex assaults on students. Those three employees were all charged in January. The federal lawsuit against Cordova is the second filed by Garcia against the district in recent weeks.

Earlier this month, Garcia filed a similar federal lawsuit against DISD in reference to Guillermo Arriaga, a 38-year-old former physical education teacher at Caceres Elementary school and boy’s basketball coach at Donna High, according to MySanAntonio.com.

The lawsuit claims school officials failed to protect the student from Arriaga, even after they suspected an inappropriate relationship and allegedly contacted the victim’s parents in October about a rumor of a sexual relationship. The parents confronted Arriaga, who claimed the two only talked.

“Arriaga allegedly snuck into the student’s house and had sex with her on Jan. 16, months after school officials spoke to her parents, according to a criminal complaint” cited by The Monitor.

“The parents told police they noticed an open gate and footprints leading to their daughter’s room later that day. When they asked her about the tracks the girl admitted to having sex with Arriaga at least five times since November, the complaint states.”

In Arriaga’s case, Garcia argues district officials violated federal Title IX laws that protects students against sex discrimination in federal education programs.

A district attorney said DISD will receive assistance in the cases from the Texas Municipal League, which provides legal guidance to thousands of Texas government agencies.

The Monitor could not reach Superintendent Reyna for comment.

A third school employee was also arrested in January over an alleged sexual relationship with a student. Arturo Castillo Jr., 34, was a truancy officer until he was charged with a 20-year felony for allegedly supplying a student with alcohol and taking her to a hotel for unprotected sex, My San Antonio reports.
